Supergirl and Regin Go Head to Head in Promo Photos from the Mid Season Finale of Supergirl

Promo photos from the mid-season finale of Supergirl have been released. The episode is called, “Reign” and it will air this coming Monday, December 4.

In the episode, “Supergirl(Melissa Benoist) investigates a mysterious symbol popping up all over National City, tracing its origins back to an ancient prophecy and the mark of the World Killer, Reign (Odetee Annable). Meanwhile, the tension between Lena (Katie McGrath) and Morgan Edge (guest star Adrian Pasdar) continues to build, causing James to step in and offer up some protection, and possibly igniting a spark in the process.”

How is it the mid-season finale already?! I feel like the season just begun!
